Effective December 11, 2017, the Animal and Plant Health Inspection Service (APHIS) and the California Department of Food and Agriculture (CDFA) established a Mexican Fruit fly (Mexfly) quarantine in the Encinitas area of San Diego County, California. APHIS is applying safeguarding measures and restrictions on the interstate movement or entry into foreign trade of regulated articles from this area.

Between November 29, 2017, and December 11, 2017, CDFA and San Diego County fruit fly program staff trapped and confirmed five adult Mexflies triggering a 65 square mile quarantine area. APHIS is working with CDFA and the San Diego County Agriculture Commissioner’s office to respond to these detections following program survey, treatment, and quarantine protocols. This action is necessary to prevent the spread of Mexfly to non-infested areas of the United States.

The establishment of this quarantine area is reflected on the following designated website, which contains a description of all the current federal fruit fly quarantine areas:
